Control of directive antennas for wireless links

A method in a radio transmitter for identifying one or more suitable probing signal transmit patterns, the method comprising the steps of:

• generating, via a processor of the radio transmitter, a probing signal;
• steering, via the processor, a probing signal transmit pattern of a steerable transmit pattern antenna according to a pre-determined sequence of probing signal transmit patterns;
• and
• transmitting the probing signal via the steerable transmit pattern antenna to identify the one or more suitable probing signal transmit patterns.

A radio receiver, the radio receiver comprising:

• a steerable receive pattern antenna;
• a processor, the processor being arranged to steer a probing signal receive pattern of the steerable receive pattern antenna according to a pre-determined sequence of probing signal receive patterns;
• and
• a receiver arranged to receive a probing signal via the steerable receive pattern antenna;
• wherein the processor further being adapted to determine a probing signal quality value from the received probing signal as a function of the pre-determined sequence of probing signal receive patterns and identify one or more suitable probing signal receive patterns based on the determined probing signal quality value.

A radio transmitter, the radio transmitter comprising:

• a steerable transmit pattern antenna;
• a transmitter;
• and
• a processor arranged to generate a probing signal, and to transmit the probing signal to the transmitter,
• wherein, the transmitter arranged to receive the probing signal from the processor and to transmit the probing signal via the steerable transmit pattern antenna, and
• wherein, the processor further adapted to steer a probing signal transmit pattern of the steerable transmit pattern antenna according to a pre-determined sequence of probing signal transmit patterns to identify one or more suitable probing signal transmit patterns.
